Psalmotoxin-1 docking to human acid-sensing ion channel-1.
Acid-sensing ion channel-1 (ASIC-1) is a proton-gated ion channel implicated in nociception and neuronal death during ischemia. Recently the first crystal structure of a chicken ASIC was obtained. Expanding upon this work, homology models of the human ASICs were constructed and evaluated. Energy-minimized structures were tested for validity by in silico docking of the models to psalmotoxin-1, w...
متن کاملAcid Sensing Ion Channel 1 in Lateral Hypothalamus Contributes to Breathing Control
Acid-sensing ion channels (ASICs) are present in neurons and may contribute to chemoreception. Among six subunits of ASICs, ASIC1 is mainly expressed in the central nervous system. Recently, multiple sites in the brain including the lateral hypothalamus (LH) have been found to be sensitive to extracellular acidification. Since LH contains orexin neurons and innervates the medulla respiratory ce...
متن کاملIon conduction and selectivity in acid-sensing ion channel 1
The ability of acid-sensing ion channels (ASICs) to discriminate among cations was assessed based on changes in conductance and reversal potential with ion substitution. Human ASIC1a was expressed in Xenopus laevis oocytes, and acid-induced currents were measured using two-electrode voltage clamp. Replacement of extracellular Na(+) with Li(+), K(+), Rb(+), or Cs(+) altered inward conductance an...
متن کاملAcid-sensing ion channel 3 in retinal function and survival.
PURPOSE Changes in extracellular pH occur in the retina and directly affect retinal activity and phototransduction. The authors analyzed the expression in rodent retina of ASIC3, a sensor of extracellular acidosis, and used ASIC3 knockout mice to explore its role in retinal function and survival. METHODS The expression and the role of ASIC3 were examined by immunolocalization and by comparing...
متن کاملCoupling between NMDA Receptor and Acid-Sensing Ion Channel Contributes to Ischemic Neuronal Death
Acid-sensing ion channels (ASICs) composed of ASIC1a subunit exhibit a high Ca(2+) permeability and play important roles in synaptic plasticity and acid-induced cell death. Here, we show that ischemia enhances ASIC currents through the phosphorylation at Ser478 and Ser479 of ASIC1a, leading to exacerbated ischemic cell death. The phosphorylation is catalyzed by Ca(2+)/calmodulin-dependent prote...
